Joseph Isadore Lieberman (1942-) was a U.S. Senator for Connecticut from 1989 until 2013. He ran unsuccessfully for Vice President on Al Gore's ticket in 2000, and unsuccessfully sought the Democratic presidential nomination in 2004. Elected to the Senate as a Democrat in 1988, 1994, and 2000, he was re-elected as an independent Democrat in 2004.
Jacob Heilbrunn has described Lieberman as 'an unreconstructed neocon', charging that: "Lieberman's most egregious mistake, of course, has been not only to endorse the Iraq War, but also never, ever to acknowledge that it was a calamitous mistake".
